WINDING MACHINE.

Application led May l,

T 0 all whom may concern.'

Be it known that l, Jnisrns D. .leren7 a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State or'Pennsylvania, have invented certain new and useful Improvements inlinding Machines, of which the tollowing is a specification.

This invention relates in general to winding machines for winding doubletaper' ended cops or Dobbins In Winding machines ot this type the taperof the end orc the winding is governed by a Shaper which controls theposition of the contact or progression wheel, and hence of the threadguide carrier with relation to the spindle, during the early stages ot'the winding operation. When it is desired to wind a cop with a differenttaper it is necessary to replace this shaper with one having the desiredpitch. Additionally such a Shaper must he replaced by another when it isdesired to use the machine to wind a cop or bobbin having a tuhe otlarger' or smaller diameter, even though its pitch or taper remains thesame.

lt is an object ot my invention to provide a shaper of novel designwhich is mounted on its support in such a mann u' as to permit otadjustments ho'th to regulate the taper oft the winding and toaccommodate the ma chine to the winding ot cops on tubes ot larger' orsmaller diameters.

It is an object of my invention to provide an improved progression rod.or progression wheel and thread guide carrying rod, which is pivotallysupported at one end and adapted to have angular adjustment laterallywith respect to the spindle.

It is a further ohject of my invention to provide adjustable .means Vforregulating the throw of my reciprocating` rod in accordance with thetaper desired and the diameter ot the tubes on which the thread is to hewound.

lt. is another object ot my invention to provide anovel device forregulating the tension on the thread as it is traversed troni the smalldiameter of' one end ot tapered winding to the large diameter :it theother end of the taper.

lt is an another object ot my invention to provide a novel means on n ythread guide carrier for engaging with the shaper and for forcing thelaterally adjustable thread guide carrier ron angularly toward thespindle.

Referring now with greater particularity to the drawings it will loeseen that my delvice is comprised. as follows:

The usual frame l, spindle 2 mounted in hearings 3 in the frame anddriven through the disk 4f, is provided. A clutch and brake mechanism 5together with a thread guide carrier and progression wheel assembly 6are also provided as shown.

The traverse har 7 is slidaloly mounted in a hearing 8 in the frame land is pivotally secured at 9 to: a link l() which in turn is pivotallysecured to a suhstantially vertically extending curved arm ll lixedlycarried by the usual roel; shaft l2. The link 10 may he connected withthe arm ll at'any of the. apertures 1.3. This provides for adjustment tovary the throw of the traverse rod. The arm 11 is curved in suoli amanner that the traverse rod is always moved forward to the same pointirrespective of the variation in the length of the throwof the rod. Thisstructure is necessary to pei'- mit the proper functioning of the clutchmechanism.

The lever 46 has atA one end thereof a laterally extending guide finger47 which is so positioned that, upon oscillation ot the lever about itspivot, the finger 47 is adapted to pass between the fingers 43 and 44.The thread to be wound is fed over fingers 48 and 44 and under thefinger 47. The other end of the lever 46 is slotted at 49 to provide aguideway for a pin 48 iiXedly connected to the traverse bar 7. Thus itwill be seen that the traversing movement of the bar 7 will result in anoscillatory movement of the lever 4G around its pivot. Then the lever 7is in its forward position, that is, when the thread is being wound onthe small end oit the tapered winding, the linger 47 will movedownwardly between the iingers 43 and 44 and take up the slack in thethread. When the bar 7 moves toward therearward position, that is, whenthe thread guide carrier moves toward the larger diameter ot' thewinding, the finger 47 will be moved outwardly V'from between thefingers releasing "the tension on the thread and permitting' the slackto be taken up in the winding ot the larger diameters of the winding. Byproperly proportioningr the arms of the lever 46 and by correctlypositioning the fingers 43 and 44 the desired tensioning' effect isobtained.

My device having been described in detail its operation will be seen tobe as follows: The cop or tube to be used is placed on the spindle andthe shaper adjusted longitudinally on its supporting rod in accordanceThe shaper is ihen rotated about the shaper rod until thc desired taperis reached. The traverse bar link is then adjusted in accordance withthe length oi' throw desired. The thread guide assembly is then movedback ard along the progression rod. The finger'37 will then come incontact with the shaper and torce the rod 23 against the tension of thespring 30 out oi. alignment with the traverse bar 7. and laterallytoward the spindle. This backward movement is continued until thecontact wheel almost touches the spindle. The thread is then fed throughthe thread guide carrier and onto the spindle and the machine is readytor the winding. As the varn is built up on the spindle, the progressionwheel contacts with the same. moving the wheel outwardly along theprogression rod and moving the finger 371outwardly along the sur'tace otthe shaper 32 until iinally the red 23 is in alignment with the bar 7 atwhich point the rear tapered end is completed. the body of the windingbeing cylindrical from thereon except for the taper ot the end which isbeing wound. The taper of both ends will naturally be of equal pitchthough opposite in direction.

When t-he thread is being wound on the ysmall end of the taper thetensioning device,

as has been described taires up the Slack; and when the thread istraversed toward the larger diameters, this slack is gradually reieased.
